# Before you start

> Pre-deployment checklist verifying environment compatibility and prerequisites for Oracle TDE.

Verify your environment meets these requirements.

## Supported hardware

* CryptoHub, `7.0.3.x` or later.

## Supported operating systems

* Linux Server (Rocky Linux 8 for this example – GUI not required):

[**https://rockylinux.org/download/**](https://rockylinux.org/download/)

* Windows 10 or later

## Required access

* An account on the CryptoHub with administrator privileges to deploy new services.
* Local administrator access on the computer where Oracle Database is installed.

## Network and firewall

* Allow outbound TCP port**2001** (default Host API port) from the computer running Oracle Database to the CryptoHub, specified by FQDN (for example, `cryptohub.example.com`) or CIDR (for example, `10.0.0.0/24`).

<Warning>
  TLS inspection or SSL proxies can break mutual TLS handshakes. Exempt the CryptoHub FQDN(s) from inspection. Configure the CryptoHub with a FQDN so the exemption applies.
</Warning>
